DNR told me he likes to see at least 3000 volts. 5000 is better. Make sure you use proper ground rod and copper wire from fencer to ground and to hot wires. He says three wires/poly tape is enough, 6 inches off ground, 18 inches then about 28 inches. He said bears do not go over fences they go under them. Keep hives at least four feet from fence because they will reach in and pull them out.

I do realize that the thread was a joke but would like to add that you can get away with far less voltage by placing 2" strips of tin foil folded over the top wire with a smear of peanut butter spread in it. Put one every 10 or 12 feet. The foil protects the peanut butter from sun and rain and the bear will lick or bite it before making it to the hives.

That bear dug up a tap box at the road that was feeding houses. I do not know if it was on the primary side of the transformer or the low voltage side feeding the houses (240 volts). You really can't see it, but his feet were burned also.

hard to imagine one leg at 120 would do that much damage. i suppose if his jaw locked down on it might. tough way to go.
